FIELD OF THE INVENTION

The invention provides inhibitors of F₁F₀-ATPases (e.g., mitochondrial F₁F₀-ATPases) and their therapeutic use. In particular, the invention provides pyrazolyl guanidine compounds that inhibit F₁F₀-ATPase, and methods of using pyrazolyl guanidine compounds as therapeutic agents to treat a number of medical conditions.

BACKGROUND

Multicellular organisms exert precise control over cell number. A balance between cell proliferation and cell death achieves this homeostasis. Cell death occurs in nearly every type of vertebrate cell via necrosis or through a suicidal form of cell death, known as apoptosis. Apoptosis is triggered by a variety of extracellular and intracellular signals that engage a common, genetically programmed death mechanism.

Multicellular organisms use apoptosis to instruct damaged or unnecessary cells to destroy themselves for the good of the organism. Control of the apoptotic process therefore is very important to normal development, for example, fetal development of fingers and toes requires the controlled removal, by apoptosis, of excess interconnecting tissues, as does the formation of neural synapses within the brain. Similarly, controlled apoptosis is responsible for the sloughing off of the inner lining of the uterus (the endometrium) at the start of menstruation. While apoptosis plays an important role in tissue sculpting and normal cellular maintenance, it is also a component of the primary defense against cells and invaders (e.g., viruses) which threaten the well being of the organism.

Not surprisingly many diseases are associated with dysregulation of apoptotic cell death. Experimental models have established a cause-effect relationship between aberrant apoptotic regulation and the pathagenicity of various neoplastic, autoimmune and viral diseases. For instance, in the cell-mediated immune response, effector cells (e.g., cytotoxic T lymphocytes “CTLs”) destroy virus-infected cells by inducing the infected cells to undergo apoptosis. The organism subsequently relies on the apoptotic process to destroy the effector cells when they are no longer needed. Autoimmunity is normally prevented by the CTLs inducing apoptosis in each other and even in themselves. Defects in this process are associated with a variety of immune diseases such as lupus erythematosus and rheumatoid arthritis.

Multicellular organisms also use apoptosis to instruct cells with damaged nucleic acids (e.g., DNA) to destroy themselves prior to becoming cancerous. Some cancer-causing viruses overcome this safeguard by reprogramming infected (transformed) cells to abort the normal apoptotic process. For example, several human papilloma viruses (HPVs) have been implicated in causing cervical cancer by suppressing the apoptotic removal of transformed cells by producing a protein (E6) which inactivates the p53 apoptosis promoter. Similarly, the Epstein-Barr virus (EBV), the causative agent of mononucleosis and Burkitt's lymphoma, reprograms infected cells to produce proteins that prevent normal apoptotic removal of the aberrant cells thus allowing the cancerous cells to proliferate and to spread throughout the organism.

Still other viruses destructively manipulate a cell's apoptotic machinery without directly resulting in the development of a cancer. For example, destruction of the immune system in individuals infected with the human immunodeficiency virus (HIV) is thought to progress through infected CD4⁺ T cells (about 1 in 100,000) instructing uninfected sister cells to undergo apoptosis.

Some cancers that arise by non-viral means have also developed mechanisms to escape destruction by apoptosis. Melanoma cells, for instance, avoid apoptosis by inhibiting the expression of the gene encoding Apaf-1. Other cancer cells, especially lung and colon cancer cells, secrete high levels of soluble decoy molecules that inhibit the initiation of CTL mediated clearance of aberrant cells. Faulty regulation of the apoptotic machinery has also been implicated in various degenerative conditions and vascular diseases.

Controlled regulation of the apoptotic process and its cellular machinery is important to the survival of multicellular organisms. Typically, the biochemical changes that occur in a cell instructed to undergo apoptosis occur in an orderly procession. However, as shown above, flawed regulation of apoptosis can cause serious deleterious effects in the organism.

The need exists for improved compositions and methods for regulating the apoptotic processes in subjects afflicted with diseases and conditions characterized by faulty regulation of these processes (e.g., viral infections, hyperproliferative autoimmune disorders, chronic inflammatory conditions, and cancers). The present invention addresses this need and provides other related advantages.

The compounds of the disclosure may contain one or more chiral centers and/or double bonds and, therefore, exist as stereoisomers, such as geometric isomers, enantiomers or diastereomers. The term “stereoisomers” when used herein consist of all geometric isomers, enantiomers or diastereomers. These compounds may be designated by the symbols “R” or “S,” depending on the configuration of substituents around the stereogenic carbon atom. Stereoisomers include enantiomers and diastereomers. Mixtures of enantiomers or diastereomers may be designated “(±)” in nomenclature, but the skilled artisan will recognize that a structure may denote a chiral center implicitly. Unless indicated otherwise, generic chemical structures and graphical representations of specific compounds encompass all stereoisomers.

Individual stereoisomers of compounds of the present invention can be prepared synthetically from commercially available starting materials that contain asymmetric or stereogenic centers, or by preparation of racemic mixtures followed by resolution methods well known to those of ordinary skill in the art. These methods of resolution are exemplified by (1) attachment of a mixture of enantiomers to a chiral auxiliary, separation of the resulting mixture of diastereomers by recrystallization or chromatography and liberation of the optically pure product from the auxiliary, (2) salt formation employing an optically active resolving agent, or (3) direct separation of the mixture of optical enantiomers on chiral chromatographic columns. Stereoisomeric mixtures can also be resolved into their component stereoisomers by well known methods, such as chiral-phase gas chromatography, chiral-phase high performance liquid chromatography, crystallizing the compound as a chiral salt complex, or crystallizing the compound in a chiral solvent. Stereoisomers can also be obtained from stereomerically-pure intermediates, reagents, and catalysts by well known asymmetric synthetic methods.

Geometric isomers can also exist in the compounds of the present invention. The symbol

denotes a bond that may be a single, double or triple bond as described herein. The present invention encompasses the various geometric isomers and mixtures thereof resulting from the arrangement of substituents around a carbon-carbon double bond or arrangement of substituents around a carbocyclic ring. Substituents around a carbon-carbon double bond are designated as being in the “Z” or “E” configuration wherein the terms “Z” and “E” are used in accordance with IUPAC standards. Unless otherwise specified, structures depicting double bonds encompass both the “E” and “Z” isomers.

Substituents around a carbon-carbon double bond alternatively can be referred to as “cis” or “trans,” where “cis” represents substituents on the same side of the double bond and “trans” represents substituents on opposite sides of the double bond. The arrangement of substituents around a carbocyclic ring are designated as “cis” or “trans.” The term “cis” represents substituents on the same side of the plane of the ring and the term “trans” represents substituents on opposite sides of the plane of the ring. Mixtures of compounds wherein the substituents are disposed on both the same and opposite sides of plane of the ring are designated “cis/trans.”

Certain compounds described herein may exist as a single tautomer or as a mixture of tautomers. For example, certain guanidine compounds having a hydrogen atom attached to at least one of the guanidine nitrogen atoms can exist as a single tautomer or a mixture of tautomers. To illustrate, depending upon the substituents attached at the R¹, R² and R³ positions, the guanidine compound may exist as a single tautomer represented by A, B, or C, or as mixture of two or more of A, B, and C.

The compounds disclosed herein can exist in solvated as well as unsolvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like, and it is intended that the invention embrace both solvated and unsolvated forms.

The invention also embraces isotopically labeled compounds of the invention which are identical to those recited herein, except that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³¹P, ³²P, ³⁵S, ¹⁸F, and ³⁶Cl, respectively.

Certain isotopically-labeled disclosed compounds (e.g., those labeled with ³H and ¹⁴C) are useful in compound and/or substrate tissue distribution assays. Tritiated (i.e., ³H) and carbon-14 (i.e., ¹⁴C) isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Isotopically labeled compounds of the invention can generally be prepared by following procedures analogous to those disclosed in the e.g., Examples herein by substituting an isotopically labeled reagent for a non-isotopically labeled reagent.

The term “IC₅₀” is art-recognized and refers to the concentration of a compound that is required for 50% inhibition of its target.

The term “EC₅₀” is art-recognized and refers to the concentration of a compound at which 50% of its maximal effect is observed.

The terms “subject” and “patient” refer to organisms to be treated by the methods of the present invention. Such organisms preferably include, but are not limited to, mammals (e.g., murines, simians, equines, bovines, porcines, canines, felines, and the like), and most preferably includes humans. In the context of the invention, the terms “subject” and “patient” generally refer to an individual who will receive or who has received treatment (e.g., administration of a compound of the present invention and optionally one or more other agents) for a condition characterized by the dysregulation of apoptotic processes.

As used herein, the term “effective amount” refers to the amount of a compound sufficient to effect beneficial or desired results. An effective amount can be administered in one or more administrations, applications or dosages and is not intended to be limited to a particular formulation or administration route. As used herein, the term “treating” includes any effect, e.g., lessening, reducing, modulating, ameliorating or eliminating, that results in the improvement of the condition, disease, disorder, and the like, or ameliorating a symptom thereof.

The phrase “pathologically proliferating or growing cells” refers to a localized population of proliferating cells in an animal that is not governed by the usual limitations of normal growth.

As used herein, the term “un-activated target cell” refers to a cell that is either in the G_(o) phase or one to which a stimulus has not been applied.

As used herein, the term “activated target lymphoid cell” refers to a lymphoid cell that has been primed with an appropriate stimulus to cause a signal transduction cascade, or alternatively, a lymphoid cell that is not in G_(o) phase. Activated lymphoid cells may proliferate, undergo activation induced cell death, or produce one or more cytotoxins, cytokines, or other related membrane-associated proteins characteristic of the cell type (e.g., CD8⁺ or CD4⁺). They are also capable of recognizing and binding any target cell that displays a particular antigen on its surface, and subsequently releasing its effector molecules.

As used herein, the term “activated cancer cell” refers to a cancer cell that has been primed with an appropriate stimulus to cause signal transduction. An activated cancer cell may or may not be in the G_(O) phase.

An activating agent is a stimulus that upon interaction with a target cell results in a signal transduction cascade. Examples of activating stimuli include, but are not limited to, small molecules, radiant energy, and molecules that bind to cell activation cell surface receptors. Responses induced by activation stimuli can be characterized by changes in, among others, intracellular Ca²⁺, superoxide, or hydroxyl radical levels; the activity of enzymes like kinases or phosphatases; or the energy state of the cell. For cancer cells, activating agents also include transforming oncogenes.

As used herein, the term “dysregulation of the process of cell death” refers to any aberration in the ability (e.g., predisposition) of a cell to undergo cell death via either necrosis or apoptosis. Dysregulation of cell death is associated with or induced by a variety of conditions, including for example, immune disorders (e.g., systemic lupus erythematosus, autoimmune disorders, rheumatoid arthritis, graft-versus-host disease, myasthenia gravis, Sjögren's syndrome, etc.), chronic inflammatory conditions (e.g., psoriasis, asthma and Crohn's disease), hyperproliferative disorders (e.g., tumors, B cell lymphomas, T cell lymphomas, etc.), viral infections (e.g., herpes, papilloma, HIV), and other conditions such as osteoarthritis and atherosclerosis.

It should be noted that when the dysregulation is induced by or associated with a viral infection, the viral infection may or may not be detectable at the time dysregulation occurs or is observed. That is, viral-induced dysregulation can occur even after the disappearance of symptoms of viral infection.

A “hyperproliferative disorder,” as used herein refers to any condition in which a localized population of proliferating cells in an animal is not governed by the usual limitations of normal growth. Examples of hyperproliferative disorders include tumors, neoplasms, lymphomas and the like. A neoplasm is said to be benign if it does not undergo invasion or metastasis and malignant if it does either of these. A metastatic cell or tissue means that the cell can invade and destroy neighboring body structures. Hyperplasia is a form of cell proliferation involving an increase in cell number in a tissue or organ, without significant alteration in structure or function. Metaplasia is a form of controlled cell growth in which one type of fully differentiated cell substitutes for another type of differentiated cell. Metaplasia can occur in epithelial or connective tissue cells. A typical metaplasia involves a somewhat disorderly metaplastic epithelium.

The pathological growth of activated lymphoid cells often results in an immune disorder or a chronic inflammatory condition. As used herein, the term “immune disorder” refers to any condition in which an organism produces antibodies or immune cells which recognize the organism's own molecules, cells or tissues. Non-limiting examples of immune disorders include autoimmune disorders, immune hemolytic anemia, immune hepatitis, Berger's disease or IgA nephropathy, Celiac Sprue, chronic fatigue syndrome, Crohn's disease, dermatomyositis, fibromyalgia, graft-versus-host disease, Grave's disease, Hashimoto's thyroiditis, idiopathic thrombocytopenia purpura, lichen planus, multiple sclerosis, myasthenia gravis, psoriasis, rheumatic fever, rheumatic arthritis, scleroderma, Sjorgren syndrome, systemic lupus erythematosus, type 1 diabetes, ulcerative colitis, vitiligo, tuberculosis, and the like.

As used herein, the term “chronic inflammatory condition” refers to a condition wherein the organism's immune cells are activated. Such a condition is characterized by a persistent inflammatory response with pathologic sequelae. This state is characterized by infiltration of mononuclear cells, proliferation of fibroblasts and small blood vessels, increased connective tissue, and tissue destruction. Examples of chronic inflammatory diseases include, but are not limited to, Crohn's disease, psoriasis, chronic obstructive pulmonary disease, inflammatory bowel disease, multiple sclerosis, and asthma. Immune diseases such as rheumatoid arthritis and systemic lupus erythematosus can also result in a chronic inflammatory state.

As used herein, the term “co-administration” refers to the administration of at least two agent(s) (e.g., a compound of the present invention) or therapies to a subject. In some embodiments, the co-administration of two or more agents/therapies is concurrent. In other embodiments, a first agent/therapy is administered prior to a second agent/therapy. Those of skill in the art understand that the formulations and/or routes of administration of the various agents/therapies used may vary. The appropriate dosage for co-administration can be readily determined by one skilled in the art. In some embodiments, when agents/therapies are co-administered, the respective agents/therapies are administered at lower dosages than appropriate for their administration alone. Thus, co-administration is especially desirable in embodiments where the co-administration of the agents/therapies lowers the requisite dosage of a known potentially harmful (e.g., toxic) agent(s).

As used herein, the term “pharmaceutical composition” refers to the combination of an active agent with a carrier, inert or active, making the composition especially suitable for diagnostic or therapeutic use in vivo or ex vivo.

As used herein, the term “pharmaceutically acceptable carrier” refers to any of the standard pharmaceutical carriers, such as a phosphate buffered saline solution, water, emulsions (e.g., such as an oil/water or water/oil emulsions), and various types of wetting agents. The compositions also can include stabilizers and preservatives. For examples of carriers, stabilizers and adjuvants. (See e.g., Martin, Remington's Pharmaceutical Sciences, 15th Ed., Mack Publ. Co., Easton, Pa. [1975]).

As used herein, the term “pharmaceutically acceptable salt” refers to any pharmaceutically acceptable salt (e.g., acid or base) of a compound of the present invention which, upon administration to a subject, is capable of providing a compound of this invention or an active metabolite or residue thereof. As is known to those of skill in the art, “salts” of the compounds of the present invention may be derived from inorganic or organic acids and bases. Examples of acids include, but are not limited to, hydrochloric, hydrobromic, sulfuric, nitric, perchloric, fumaric, maleic, phosphoric, glycolic, lactic, salicylic, succinic, toluene-p-sulfonic, tartaric, acetic, citric, methanesulfonic, ethanesulfonic, formic, benzoic, malonic, naphthalene-2-sulfonic, benzenesulfonic acid, and the like. Other acids, such as oxalic, while not in themselves pharmaceutically acceptable, may be employed in the preparation of salts useful as intermediates in obtaining the compounds of the invention and their pharmaceutically acceptable acid addition salts.

Examples of bases include, but are not limited to, alkali metals (e.g., sodium) hydroxides, alkaline earth metals (e.g., magnesium), hydroxides, ammonia, and compounds of formula NW₄ ⁺, wherein W is C₁₋₄ alkyl, and the like.

Examples of salts include, but are not limited to: acetate, adipate, alginate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, citrate, camphorate, camphorsulfonate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, fumarate, flucoheptanoate, glycerophosphate, hemisulfate, heptanoate, hexanoate, hydrochloride, hydrobromide, hydroiodide, 2-hydroxyethanesulfonate, lactate, maleate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, oxalate, palmoate, pectinate, persulfate, phenylpropionate, picrate, pivalate, propionate, succinate, tartrate, thiocyanate, tosylate, undecanoate, and the like. Other examples of salts include anions of the compounds of the present invention compounded with a suitable cation such as Na⁺, NH₄ ⁺, and NW₄ ⁺ (wherein W is a C₁₋₄ alkyl group), and the like.

For therapeutic use, salts of the compounds of the present invention are contemplated as being pharmaceutically acceptable. However, salts of acids and bases that are non-pharmaceutically acceptable may also find use, for example, in the preparation or purification of a pharmaceutically acceptable compound.

As used herein, the term “modulate” refers to the activity of a compound (e.g., a compound of the present invention) to affect (e.g., to promote or retard) an aspect of cellular function, including, but not limited to, cell growth, proliferation, apoptosis, and the like.

Throughout the description, where compositions are described as having, including, or comprising specific components, or where processes and methods are described as having, including, or comprising specific steps, it is contemplated that, additionally, there are compositions of the present invention that consist essentially of, or consist of, the recited components, and that there are processes and methods according to the present invention that consist essentially of, or consist of, the recited processing steps.

As a general matter, compositions specifying a percentage are by weight unless otherwise specified. Further, if a variable is not accompanied by a definition, then the previous definition of the variable controls.

I. Modulators of F₁F₀-ATPase Activity

In some embodiments, the present invention regulates F₁F₀-ATPase activity (e.g., mitochondrial F₁F₀-ATPase activity) through the exposure of cells to compounds of the present invention. In some embodiments, the compounds inhibit ATP synthesis and ATP hydrolysis. The effect of the compounds can be measured by detecting any number of cellular changes. For example, mitochondrial F₁F₀-ATPase activity and/or cell death may be assayed as described herein and in the art. In some embodiments, cell lines are maintained under appropriate cell culturing conditions (e.g., gas (CO₂), temperature and media) for an appropriate period of time to attain exponential proliferation without density dependent constraints. Cell number and or viability are measured using standard techniques, such as trypan blue exclusion/hemo-cytometry, or an Alamar Blue or MTT dye conversion assay. Alternatively, the cell may be analyzed for the expression of genes or gene products associated with aberrations in apoptosis or necrosis.

In some embodiments, exposing the compounds of the present invention to a cell induces apoptosis. In some embodiments, the present invention induces apoptosis or arrest of cell proliferation through interacting with the mitochondrial F₁F₀-ATPase. In some embodiments, the compounds of the present invention inhibit mitochondrial F₁F₀-ATPase activity through binding the OSCP. In some embodiments, the compounds of the present invention bind the junction between the OSCP and the F₁ subunit of the mitochondrial F₁F₀-ATPase. In some embodiments, the compounds of the present invention bind the F₁ subunit. In certain embodiments, screening assays of the present invention permit detection of binding partners of the OSCP, F₁, or OSCP/F₁ junction.

In some embodiments, exposing a compound of the present invention to a cell induces apoptosis. In some embodiments, the present invention causes an initial increase in cellular ROS levels (e.g., O₂ ⁻). In further embodiments, exposure of the compounds of the present invention to a cell causes an increase in cellular O₂ ⁻ levels. In still further embodiments, the increase in cellular O₂ ⁻ levels resulting from the compounds of the present invention is detectable with a redox-sensitive agent that reacts specifically with O₂ ⁻ (e.g., dihydroethidium (DHE)).

In some embodiments, the present invention causes a collapse of a cell's mitochondrial transmembrane potential (ΔΨ_(m)). In some embodiments, a collapse of a cell's mitochondrial ΔΨ_(m) resulting from the present invention is detectable with a mitochondria-selective potentiometric probe (e.g., 3,3′-Dihexyloxacarbocyanine iodide, DiOC₆). In further embodiments, a collapse of a cell's mitochondrial ΔΨ_(m) resulting from the present invention occurs after an initial increase in cellular O₂ ⁻ levels.

In some embodiments, the present invention enables caspase activation. In other embodiments, the present invention causes the release of cytochrome c from mitochondria. In further embodiments, the present invention alters cystolic cytochrome c levels. In still other embodiments, altered cystolic cytochrome c levels resulting from the present invention are detectable by immunoblotting cytosolic fractions. In some embodiments, diminished cystolic cytochrome c levels resulting from the present invention are detectable after a period of time (e.g., 10 hours). In further preferred embodiments, diminished cystolic cytochrome c levels resulting from the present invention are detectable after 5 hours.

In other embodiments, the present invention causes the opening of the mitochondrial permeability transition pore. In some embodiments, the cellular release of cytochrome c resulting from the present invention is consistent with a collapse of mitochondrial ΔΨ_(m). In still further preferred embodiments, the present invention causes an increase in cellular O₂ ⁻ levels after a mitochondrial ΔΨ_(m) collapse and a release of cytochrome c. In further preferred embodiments, a rise in cellular O₂ ⁻ levels is caused by a mitochondrial ΔΨ_(m) collapse and release of cytochrome c resulting from the present invention.

In other embodiments, the present invention causes cellular caspase activation. In some embodiments, caspase activation resulting from the present invention is measurable with a pan-caspase sensitive fluorescent substrate (e.g., FAM-VAD-fmk). In still further embodiments, caspase activation resulting from the present invention tracks with a collapse of mitochondrial ΔΨ_(m). In other embodiments, the present invention causes an appearance of hypodiploid DNA. In some embodiments, an appearance of hypodiploid DNA resulting from the present invention is slightly delayed with respect to caspase activation.

In some embodiments, the molecular target for the present invention is found within mitochondria. In further embodiments, the molecular target of the present invention involves the mitochondrial ATPase. The primary sources of cellular ROS include redox enzymes and the mitochondrial respiratory chain (hereinafter MRC). In some embodiments, cytochrome c oxidase (complex IV of the MRC) inhibitors (e.g., NaN₃) preclude a present invention dependent increase in cellular ROS levels. In other preferred embodiments, the ubiquinol-cytochrome c reductase component of MRC complex III inhibitors (e.g., FK506) preclude a present invention dependent increase in ROS levels.

In certain other embodiments, the compound is one of the compounds listed in Examples 1-18, or a pharmaceutically acceptable salt of said compounds. It is understood that the foregoing compounds can be combined with a pharmaceutically acceptable carrier to produce a pharmaceutical composition.

Exemplary methods for preparing compounds described herein are provided in the examples. Further exemplary procedures for making various compounds described herein are described in Scheme 1 below. The synthetic scheme is provided for the purpose of illustrating the invention, but not for limiting the scope or spirit of the invention. Starting materials can be obtained from commercial sources or be prepared based on procedures described in the literature.

The synthetic route in Scheme 1 involves reacting an optionally substituted benzoylchloride with potassium thiocyanate to form an acyl isothiocyanate intermediate. This acyl isothiocyanate intermediate is treated with an amino-pyrazole compound to form an acyl thiourea. The acyl thiourea is reacted with 1-ethyl-2′,2′-dimethylaminopropylcarbodiimide (EDCI) and a second amine compound (e.g., an aniline or benzylamine) to form the desired pyrazolyl guanidine compound. To the extent either the amino-pyrazole or the second amine compound contain a further functional group that may undergo reaction under the conditions illustrated in Scheme 1, standard protecting group strategies for protection and deprotection may be employed. See, for example, Greene, T. W.; Wuts, P.G.M. Protective Groups in Organic Synthesis, 2^(nd) ed.; Wiley: New York, 1991. It understood that the optionally substituted benzoylchloride starting material can be replaced with a heteroaryl acid chloride (i.e., nicotinoyl chloride) to prepare pyrazolyl guanidines containing a —C(O)-heteroaryl moiety.

In certain embodiments, the guanidine compounds described herein are used to treat a subject suffering from a Trypanosoma brucei infection.

The antibacterial activity of the compounds described herein may be evaluated using standard assays known in the art, such as the microbroth dilution minimum inhibition concentration (MIC) assay, as further described in National Committee for Clinical Laboratory Standards. Performance Standards for Antimicrobial Susceptibility Testing; Fourteenth Informational Supplement. NCCLS document M100-S14 {ISBN 1-56238-516-X}. This assay may be used to determine the minimum concentration of a compound necessary to prevent visible bacterial growth in a solution. In general, the drug to be tested is serially diluted into wells, and aliquots of liquid bacterial culture are added. This mixture is incubated under appropriate conditions, and then tested for growth of the bacteria. Compounds with low or no antibiotic activity (a high MIC) will allow growth at high concentrations of compound, while compounds with high antibiotic activity will allow bacterial growth only at lower concentrations (a low MIC).

The assay uses stock bacterial culture conditions appropriate for the chosen strain of bacteria. Stock cultures from the permanent stock culture collection can be stored as frozen suspensions at −70° C. Cultures may be suspended in 10% skim milk (BD) prior to snap freezing in dry ice/ethanol and then placed in a −70° C. freezer. Cultures may be maintained on Tryptic Soy Agar containing 5% Sheep Blood at room temperature (20° C.), and each culture may be recovered from frozen form and transferred an additional time before MIC testing. Fresh plates are inoculated the day before testing, incubated overnight, and checked to confirm purity and identity.

The identity and purity of the cultures recovered from the stock culture can be confirmed to rule out the possibility of contamination. The identity of the strains may be confirmed by standard microbiological methods (See, e.g., Murray et al., Manual of Clinical Microbiology, Eighth Edition. ASM Press {ISBN 1-55581-255-4}). In general, cultures are streaked onto appropriate agar plates for visualization of purity, expected colony morphology, and hemolytic patterns. Gram stains can also be utilized. The identities are confirmed using a MicroScan WalkAway 40 SI Instrument (Dade Behring, West Sacramento, Calif.). This device utilizes an automated incubator, reader, and computer to assess for identification purposes the biochemical reactions carried out by each organism. The MicroScan WalkAway can also be used to determine a preliminary MIC, which may be confirmed using the method described below.

Frozen stock cultures may be used as the initial source of organisms for performing microbroth dilution minimum inhibition concentration (MIC) testing. Stock cultures are passed on their standard growth medium for at least 1 growth cycle (18-24 hours) prior to their use. Most bacteria may be prepared directly from agar plates in 10 mL aliquots of the appropriate broth medium. Bacterial cultures are adjusted to the opacity of a 0.5 McFarland Standard (optical density value of 0.28-0.33 on a Perkin-Elmer Lambda EZ150 Spectrophotometer, Wellesley, Mass., set at a wavelength of 600 nm). The adjusted cultures are then diluted 400 fold (0.25 mL inoculum+100 mL broth) in growth media to produce a starting suspension of approximately 5×105 colony forming units (CFU)/mL. Most bacterial strains may be tested in cation adjusted Mueller Hinton Broth (CAMHB).

Test compounds (“drugs”) are solubilized in a solvent suitable for the assay, such as DMSO. Drug stock solutions may be prepared on the day of testing. Microbroth dilution stock plates may be prepared in two dilution series, 64 to 0.06 μg drug/mL and 0.25 to 0.00025 μg drug/mL. For the high concentration series, 200 μL of stock solution (2 mg/mL) is added to duplicate rows of a 96-well microtiter plate. This is used as the first well in the dilution series. Serial two-fold decremental dilutions are made using a BioMek FX robot (Beckman Coulter Inc., Fullerton, Calif.) with 10 of the remaining 11 wells, each of which will contain 100 μL of the appropriate solvent/diluent. Row 12 contains solvent/diluent only and serves as the control. For the first well of the low concentration series, 200 μL of an 8 μg/mL stock are added to duplicate rows of a 96-well plate. Serial two-fold dilutions are made as described above.

Daughter 96-well plates may be spotted (3.2 μL/well) from the stock plates listed above using the BioMek FX robot and used immediately or frozen at −70° C. until use. Aerobic organisms are inoculated (100 μL volumes) into the thawed plates using the BioMek FX robot. The inoculated plates are be placed in stacks and covered with an empty plate. These plates are then incubated for 16 to 24 hours in ambient atmosphere according to CLSI guidelines (National Committee for Clinical Laboratory Standards, Methods for Dilution, Antimicrobial Tests for Bacteria that Grow Aerobically; Approved Standard-Sixth Edition. NCCLS document M7-A6 {ISBN 1-56238-486-4}).

After inoculation and incubation, the degree of bacterial growth can be estimated visually with the aid of a Test Reading Mirror (Dynex Technologies 220 16) in a darkened room with a single light shining directly through the top of the microbroth tray. The MIC is the lowest concentration of drug that prevents macroscopically visible growth under the conditions of the test.

Additionally, any one or more of the pyrazolyl guanidine compounds described herein can be used to treat a F₁F₀-ATP hydrolase associated disorder (e.g., myocardial infarction, ventricular hypertrophy, coronary artery disease, non-Q wave MI, congestive heart failure, cardiac arrhythmias, unstable angina, chronic stable angina, Prinzmetal's angina, high blood pressure, intermittent claudication, peripheral occlusive arterial disease, thrombotic or thromboembolic symptoms of thromboembolic stroke, venous thrombosis, arterial thrombosis, cerebral thrombosis, pulmonary embolism, cerebral embolism, thrombophilia, disseminated intravascular coagulation, restenosis, atrial fibrillation, ventricular enlargement, atherosclerotic vascular disease, atherosclerotic plaque rupture, atherosclerotic plaque formation, transplant atherosclerosis, vascular remodeling atherosclerosis, cancer, surgery, inflammation, systematic infection, artificial surfaces, interventional cardiology, immobility, medication, pregnancy and fetal loss, and diabetic complications comprising retinopathy, nephropathy and neuropathy) in a subject.

One of skill in the art will appreciate that any one or more of the compounds described herein, including the many specific embodiments, are prepared by applying standard pharmaceutical manufacturing procedures. Such medicaments can be delivered to the subject by using delivery methods that are well-known in the pharmaceutical arts.

B. Exemplary Pharmaceutical Compositions and Formulation

In some embodiments of the present invention, the compositions are administered alone, while in some other embodiments, the compositions are preferably present in a pharmaceutical formulation comprising at least one active ingredient/agent, as discussed above, together with a solid support or alternatively, together with one or more pharmaceutically acceptable carriers and optionally other therapeutic agents (e.g., those described in section III hereinabove). Each carrier should be “acceptable” in the sense that it is compatible with the other ingredients of the formulation and not injurious to the subject.

Contemplated formulations include those suitable for oral, rectal, nasal, topical (including transdermal, buccal and sublingual), vaginal, parenteral (including subcutaneous, intramuscular, intravenous and intradermal) and pulmonary administration. In some embodiments, formulations are conveniently presented in unit dosage form and are prepared by any method known in the art of pharmacy. Such methods include the step of bringing into association the active ingredient with the carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association (e.g., mixing) the active ingredient with liquid carriers or finely divided solid carriers or both, and then if necessary shaping the product.

Formulations of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets, wherein each preferably contains a predetermined amount of the active ingredient; as a powder or granules; as a solution or suspension in an aqueous or non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. In other embodiments, the active ingredient is presented as a bolus, electuary, or paste, etc.

In some embodiments, tablets comprise at least one active ingredient and optionally one or more accessory agents/carriers are made by compressing or molding the respective agents. In some embodiments, compressed tablets are prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with a binder (e.g., povidone, gelatin, hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (e.g., sodium starch glycolate, cross-linked povidone, cross-linked sodium carboxymethyl cellulose) surface-active or dispersing agent. Molded tablets are made by molding in a suitable machine a mixture of the powdered compound (e.g., active ingredient) moistened with an inert liquid diluent. Tablets may optionally be coated or scored and may be formulated so as to provide slow or controlled release of the active ingredient therein using, for example, hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile. Tablets may optionally be provided with an enteric coating, to provide release in parts of the gut other than the stomach.

Formulations suitable for topical administration in the mouth include lozenges comprising the active ingredient in a flavored basis, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert basis such as gelatin and glycerin, or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.

Pharmaceutical compositions for topical administration according to the present invention are optionally formulated as ointments, creams, suspensions, lotions, powders, solutions, pastes, gels, sprays, aerosols or oils. In alternative embodiments, topical formulations comprise patches or dressings such as a bandage or adhesive plasters impregnated with active ingredient(s), and optionally one or more excipients or diluents. In some embodiments, the topical formulations include a compound(s) that enhances absorption or penetration of the active agent(s) through the skin or other affected areas. Examples of such dermal penetration enhancers include dimethylsulfoxide (DMSO) and related analogues.

If desired, the aqueous phase of a cream base includes, for example, at least about 30% w/w of a polyhydric alcohol, i.e., an alcohol having two or more hydroxyl groups such as propylene glycol, butane-1,3-diol, mannitol, sorbitol, glycerol and polyethylene glycol and mixtures thereof.

In some embodiments, oily phase emulsions of this invention are constituted from known ingredients in a known manner. This phase typically comprises a lone emulsifier (otherwise known as an emulgent), it is also desirable in some embodiments for this phase to further comprise a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil.

Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier so as to act as a stabilizer. In some embodiments it is also preferable to include both an oil and a fat. Together, the emulsifier(s) with or without stabilizer(s) make up the so-called emulsifying wax, and the wax together with the oil and/or fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the cream formulations.

Emulgents and emulsion stabilizers suitable for use in the formulation of the present invention include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate and sodium lauryl sulfate.

The choice of suitable oils or fats for the formulation is based on achieving the desired properties (e.g., cosmetic properties), since the solubility of the active compound/agent in most oils likely to be used in pharmaceutical emulsion formulations is very low. Thus creams should preferably be non-greasy, non-staining and washable products with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters known as Crodamol CAP may be used, the last three being preferred esters. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils can be used.

Formulations suitable for topical administration to the eye also include eye drops wherein the active ingredient is dissolved or suspended in a suitable carrier, especially an aqueous solvent for the agent.

Formulations for rectal administration may be presented as a suppository with suitable base comprising, for example, cocoa butter or a salicylate.

Formulations suitable for vaginal administration may be presented as pessaries, creams, gels, pastes, foams or spray formulations containing in addition to the agent, such carriers as are known in the art to be appropriate.

Formulations suitable for nasal administration, wherein the carrier is a solid, include coarse powders having a particle size, for example, in the range of about 20 to about 500 microns which are administered in the manner in which snuff is taken, i.e., by rapid inhalation (e.g., forced) through the nasal passage from a container of the powder held close up to the nose. Other suitable formulations wherein the carrier is a liquid for administration include, but are not limited to, nasal sprays, drops, or aerosols by nebulizer, and include aqueous or oily solutions of the agents.

Formulations suitable for parenteral administration include aqueous and non-aqueous isotonic sterile injection solutions which may contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents, and liposomes or other microparticulate systems which are designed to target the compound to blood components or one or more organs. In some embodiments, the formulations are presented/formulated in unit-dose or multi-dose sealed containers, for example, ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.

Preferred unit dosage formulations are those containing a daily dose or unit, daily subdose, as herein above-recited, or an appropriate fraction thereof, of an agent.

It should be understood that in addition to the ingredients particularly mentioned above, the formulations of this invention may include other agents conventional in the art having regard to the type of formulation in question, for example, those suitable for oral administration may include such further agents as sweeteners, thickeners and flavoring agents. It also is intended that the agents, compositions and methods of this invention be combined with other suitable compositions and therapies. Still other formulations optionally include food additives (suitable sweeteners, flavorings, colorings, etc.), phytonutrients (e.g., flax seed oil), minerals (e.g., Ca, Fe, K, etc.), vitamins, and other acceptable compositions (e.g., conjugated linoelic acid), extenders, and stabilizers, etc.

C. Exemplary Administration Routes and Dosing Considerations

Various delivery systems are known and can be used to administer therapeutic agents (e.g., exemplary compounds as described above) of the present invention, e.g., encapsulation in liposomes, microparticles, microcapsules, receptor-mediated endocytosis, and the like. Methods of delivery include, but are not limited to, intra-arterial, intra-muscular, intravenous, intranasal, and oral routes. In specific embodiments, it may be desirable to administer the pharmaceutical compositions of the invention locally to the area in need of treatment; this may be achieved by, for example, and not by way of limitation, local infusion during surgery, injection, or by means of a catheter.

The agents identified can be administered to subjects or individuals susceptible to or at risk of developing pathological growth of target cells and correlated conditions. When the agent is administered to a subject such as a mouse, a rat or a human patient, the agent can be added to a pharmaceutically acceptable carrier and systemically or topically administered to the subject. To identify patients that can be beneficially treated, a tissue sample is removed from the patient and the cells are assayed for sensitivity to the agent.

Therapeutic amounts are empirically determined and vary with the pathology being treated, the subject being treated and the efficacy and toxicity of the agent. When delivered to an animal, the method is useful to further confirm efficacy of the agent. One example of an animal model is MLR/MpJ-lpr/lpr (“MLR-lpr”) (available from Jackson Laboratories, Bar Harbor, Me.). MLR-lpr mice develop systemic autoimmune disease. Alternatively, other animal models can be developed by inducing tumor growth, for example, by subcutaneously inoculating nude mice with about 10⁵ to about 10⁹ hyperproliferative, cancer or target cells as defined herein. When the tumor is established, the compounds described herein are administered, for example, by subcutaneous injection around the tumor. Tumor measurements to determine reduction of tumor size are made in two dimensions using venier calipers twice a week. Other animal models may also be employed as appropriate. Such animal models for the above-described diseases and conditions are well-known in the art.

In some embodiments, in vivo administration is effected in one dose, continuously or intermittently throughout the course of treatment. Methods of determining the most effective means and dosage of administration are well known to those of skill in the art and vary with the composition used for therapy, the purpose of the therapy, the target cell being treated, and the subject being treated. Single or multiple administrations are carried out with the dose level and pattern being selected by the treating physician.

Suitable dosage formulations and methods of administering the agents are readily determined by those of skill in the art. Preferably, the compounds are administered at about 0.01 mg/kg to about 200 mg/kg, more preferably at about 0.1 mg/kg to about 100 mg/kg, even more preferably at about 0.5 mg/kg to about 50 mg/kg. When the compounds described herein are co-administered with another agent (e.g., as sensitizing agents), the effective amount may be less than when the agent is used alone.

The pharmaceutical compositions can be administered orally, intranasally, parenterally or by inhalation therapy, and may take the form of tablets, lozenges, granules, capsules, pills, ampoules, suppositories or aerosol form. They may also take the form of suspensions, solutions and emulsions of the active ingredient in aqueous or non-aqueous diluents, syrups, granulates or powders. In addition to an agent of the present invention, the pharmaceutical compositions can also contain other pharmaceutically active compounds or a plurality of compounds of the invention.

More particularly, an agent of the present invention also referred to herein as the active ingredient, may be administered for therapy by any suitable route including, but not limited to, oral, rectal, nasal, topical (including, but not limited to, transdermal, aerosol, buccal and sublingual), vaginal, parental (including, but not limited to, subcutaneous, intramuscular, intravenous and intradermal) and pulmonary. It is also appreciated that the preferred route varies with the condition and age of the recipient, and the disease being treated.

Ideally, the agent should be administered to achieve peak concentrations of the active compound at sites of disease. This may be achieved, for example, by the intravenous injection of the agent, optionally in saline, or by oral administration, for example, as a tablet, capsule or syrup containing the active ingredient.

Desirable blood levels of the agent may be maintained by a continuous infusion to provide a therapeutic amount of the active ingredient within disease tissue. The use of operative combinations is contemplated to provide therapeutic combinations requiring a lower total dosage of each component than may be required when each individual therapeutic compound or drug is used alone, thereby reducing adverse effects.

D. Exemplary Co-administration Routes and Dosing Considerations

The invention also includes methods involving co-administration of the compounds described herein with one or more additional active agents. Indeed, it is a further aspect of this invention to provide methods for enhancing prior art therapies and/or pharmaceutical compositions by co-administering a compound of this invention. In co-administration procedures, the agents may be administered concurrently or sequentially. In one embodiment, the compounds described herein are administered prior to the other active agent(s). The pharmaceutical formulations and modes of administration may be any of those described above. In addition, the two or more co-administered chemical agents, biological agents or radiation may each be administered using different modes or different formulations.

The agent or agents to be co-administered depend on the type of condition being treated. For example, when the condition being treated is cancer, the additional agent can be a chemotherapeutic agent or radiation. When the condition being treated is an immune disorder, the additional agent can be an immunosuppressant or an anti-inflammatory agent. When the condition being treated is chronic inflammation, the additional agent can be an anti-inflammatory agent. The additional agents to be co-administered, such as anticancer, immunosuppressant, anti-inflammatory, can be any of the well-known agents in the art, including, but not limited to, those that are currently in clinical use. The determination of appropriate type and dosage of radiation treatment is also within the skill in the art or can be determined with relative ease.

Treatment of the various conditions associated with abnormal apoptosis is generally limited by the following two major factors: (1) the development of drug resistance and (2) the toxicity of known therapeutic agents. In certain cancers, for example, resistance to chemicals and radiation therapy has been shown to be associated with inhibition of apoptosis. Some therapeutic agents have deleterious side effects, including non-specific lymphotoxicity, renal and bone marrow toxicity.

The methods described herein address both these problems. Drug resistance, where increasing dosages are required to achieve therapeutic benefit, is overcome by co-administering the compounds described herein with the known agent. The compounds described herein sensitize target cells to known agents (and vice versa) and, accordingly, less of these agents are needed to achieve a therapeutic benefit.

The sensitizing function of the claimed compounds also addresses the problems associated with toxic effects of known therapeutics. In instances where the known agent is toxic, it is desirable to limit the dosages administered in all cases, and particularly in those cases where drug resistance has increased the requisite dosage. When the claimed compounds are co-administered with the known agent, they reduce the dosage required which, in turn, reduces the deleterious effects.

EXAMPLES

The invention now being generally described, will be more readily understood by reference to the following examples, which are included merely for purposes of illustration of certain aspects and embodiments of the present invention, and are not intended to limit the invention.

Example 1—Preparation of Pyrazolyl Guanidine Compounds

Described below are exemplary, general synthetic procedures for making pyrazolyl guanidine compounds, along with an exemplary synthetic procedure for making the specific pyrazolyl guanidine compound (Z)-4-chloro-N-(((3,4,5-trifluorobenzyl)amino)((3-(trifluoromethyl)-1H-pyrazol-5-yl)amino)methylene)benzamide.

Part I: General Method for Making Pyrazolyl Guandine Compounds

Guanidines can be prepared from an acid chloride, a first amine, and a second amine using a three-step procedure. First, the requisite acid chloride is combined with potassium thiocyanate in an organic solvent, and this mixture is stirred at ambient temperature for 1-4 hours. The resulting mixture is concentrated in vacuo and used immediately.

In a second step, an appropriate first amine (RNH₂) is dissolved in an organic solvent, such as methylene chloride, at ambient temperature and the acyl isothiocyanate from the first step is added. The resulting mixture is stirred at ambient temperature for 8-16 hours. The solvents are evaporated in vacuo and the resulting residue treated with a warm non-polar organic solvent, then allowed to cool and collected by filtration. The collected residue is rinsed with a non-polar organic solvent and dried. The resulting residue can be used without further purification. Alternatively, the first amine in the form of a hydrochloride salt is dissolved in an organic solvent and treated with a hindered organic base such as triethylamine then stirred at ambient temperature for 1-4 hours. The acyl isothiocyanate from step 1 is then added and the reaction mixture stirred at ambient temperature for 8-16 hours. The solvents are removed in vacuo and the resulting residue is purified by chromatography.

In the third step, the acyl thiourea from step 2 and an appropriate second amine (R¹—NH₂) are dissolved in a polar organic solvent such as dimethylformamide at ambient temperature to form a mixture. To this mixture, 1-ethyl-2′,2′-dimethylaminopropylcarbodiimide is added and the resulting mixture is stirred until the reaction appears complete by HPLC analysis of aliquots of the reaction mixture. Typical reaction times range from 30 minutes to 12 hours, and the reaction mixture may be heated (e.g., to approximately 60° C.) to accelerate the reaction. Once the reaction appears to be complete by HPLC analysis, the reaction mixture is diluted with an organic solvent (such as ethylacetate), washed with water, washed with brine, and the organic layer is dried over an appropriate drying agent, filtered, and the solvents removed under reduced pressure. The desired product can be purified by chromatography if necessary.

Part I: Alternative General Method for Making Pyrazolyl Guandine Compounds

Acyl guanidines can be prepared from an acid chloride, a first amine, and a second amine using a three-step, 2-pot procedure. First, the requisite acid chloride is combined with a slight molar excess of potassium thiocyanate in a polar aprotic solvent (such as acetonitrile) at a temperature in the range of from about 0° C. to room temperature. The resulting mixture is stirred for a time period ranging from 15 minutes to 2 hours to provide a reaction mixture containing the acyl isothiocyanate synthetic intermediate compound. This reaction mixture may be used directly in the next reaction or filtered to remove the potassium chloride generated during this first step.

In a second step, the acyl isothiocyanate compound is combined with a second amine (which may be dissolved in a solvent) to provide a reaction mixture that is stirred for a time period ranging from 15 minutes to 2 hours to produce an acyl thiourea product. The acyl thiourea product often precipitates from the reaction mixture and may be collected by filtration. Water may be added to the reaction mixture (typically in amount equal to the volume of organic solvent) to facilitate collection of the acyl thiourea product. The acyl thiourea product is dried in vacuo at approximately ambient temperature.

In a third step, the acyl thiourea product is combined with a coupling agent (such as N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide (EDCI)) and a second amine to produce the acyl guanidine. All starting materials for this reaction may be combined prior to heating the reaction mixture or the EDCI may be added last, once the temperature of the reaction mixture has been raised. Alternatively, the second amine may be added last after combining the thiourea and the EDCI. Once all the starting materials have been combined, the reaction mixture is generally stirred for a time period ranging from about 30 minutes to about 3 hours while the reaction mixture is heated to a temperature ranging from about 45° C. to about 70° C.

Part II: Exemplary Synthetic Procedure for Preparing Pyrazolyl Compound N-(((3-(4-(benzyloxy)-2-fluorophenyl)-1H-pyrazol-5-yl)amino)(cyclopentylamino)methylene)-4-(trifluoromethyl)benzamide Step A: Preparation of 4-(Benzyloxy)-2-fluorobenzoyl chloride

4-Benzyloxy-2-fluoro-benzoic acid (2 g, 8.12 mmol) was suspended in thionyl chloride (5.9 mL) and heated to reflux for 30 minutes. The reaction mixture was then concentrated under reduced pressure, and the resulting residue was dissolved in toluene and re-concentrated twice to remove residual thionyl chloride. This procedure provided the title compound in crude form, which was used in the next reaction without further purification.

Step B: Preparation of 3-(4-(Benzyloxy)-2-fluorophenyl)-3-oxopropanenitrile

Acetonitrile (1.66 mL, 31.7 mmol) was dissolved in dry THF (40 mL) and the mixture was cooled to −78 C. Butyllithium (2.5 M, 9.5 mL, 23.8 mmol) was added dropwise, and the resulting reaction mixture was stirred for 15 minutes. A solution of 4-(benzyloxy)-2-fluorobenzoyl chloride (2.1 g, 7.93 mmol) in THF was then added dropwise to the reaction mixture, and the resulting reaction mixture was stirred at −78 C for 40 minutes. Saturated ammonium chloride solution was then added carefully to the reaction mixture, and the resulting mixture was allowed to warm to room temperature. Next, the mixture was partitioned between water and EtOAc, and the organic portion was washed further with brine, then dried over sodium sulfate, and concentrated onto silica gel and purified by chromatography (gradient: 9:1 EtOAc:hexanes to 1:1 EtOAc:hexanes to 100% ethyl acetate) to give the title compound in 79% yield.

Step C: Preparation of 3-(4-(Benzyloxy)-2-fluorophenyl)-1H-pyrazol-5-amine

3-(4-(Benzyloxy)-2-fluorophenyl)-3-oxopropanenitrile (1.7 g, 6.3 mmol) was dissolved in ethanol (21 mL), and then hydrazine (0.22 mL, 6.9 mmol) was added. The reaction mixture was stirred at room temperature for about one hour, and the progress of the reaction was followed by thin-layer chromatography. If no progress had been made, the temperature was gradually increased until the reaction began proceeding. As soon as the reaction appeared complete by thin-layer chromatography, the crude material was concentrated in vacuo and purified by chromatography to provide the title compound 97% yield.

Step D: Preparation of N-(3-(4-(Benzyloxy)-2-fluorophenyl)-1H-pyrazol-5-ylcarbamothioyl)-4-(trifluoromethyl)benzamide

4-Trifluoromethylbenzoyl chloride (590 mg, 2.83 mmol) was dissolved in acetonitrile (˜30 mL) and potassium thiocyanate (302 mg, 3.22 mmol) was added to provide a reaction mixture. The reaction mixture was stirred at room temperature for 30 minutes, and then 3-(4-benzyloxy-2-fluoro-phenyl)-1H-pyrazol-5-amine (801 mg, 2.83 mmol) was added to the reaction mixture. Next, the reaction mixture was stirred at room temperature overnight, then concentrated in vacuo, slurried with water, and collected by filtration. The wet solid was held under heated vacuum for 24 hours to provide the title compound in 81% yield.

Step E: Preparation of N-(((3-(4-(Benzyloxy)-2-fluorophenyl)-1H-pyrazol-5-yl)amino)(cyclopentylamino)methylene)-4-(trifluoromethyl)benzamide

N-((3-(4-(Benzyloxy)-2-fluorophenyl)-1H-pyrazol-5-yl)carbamothioyl)-4-(trifluoromethyl)benzamide (154 mg, 0.3 mmol) and EDCI (63 mg, 0.33 mmol) were suspended in THF (4 mL) and cyclopentylamine (0.044 mL, 0.45 mmol) was added. The resulting mixture was stirred at 50° C. for 45 minutes, then concentrated onto silica gel and purified by chromatography (gradient: 9:1 hexanes:EtOAc to 6:4 hexanes:EtOAc) to provide the title compound in 53% yield.

Step F: Preparation of N-(((3-(4-(Benzyloxy)-2-fluorophenyl)-1H-pyrazol-5-yl)amino)(cyclopentylamino)methylene)-4-(trifluoromethyl)benzamide

N-(((3-(4-(Benzyloxy)-2-fluorophenyl)-1H-pyrazol-5-yl)amino)(cyclopentylamino) methylene)-4-(trifluoromethyl)benzamide (90 mg, 0.16 mmol) was dissolved in methanol (2 mL), and nitrogen gas was bubbled through briefly. 10% Palladium on carbon (84 mg) was then added to the reaction mixture, followed by the addition of ammonium formate (50 mg, 0.8 mmol). The reaction vessel was sealed and then heated to 65° C. for 1 hour. Next, the reaction mixture was cooled, and then filtered through a plug of celite. The filtrate was concentrated onto silica gel, and the product purified by chromatography to give the title compound in 12% yield.
